C# - Real-Time Database Update At Specified Time
Mar 31, 2011Given a Database that has a table Called [Bid Transactions], which contains records of all available auctions that are currently running on an ASP.net website .. something similar to Ebay.com, when the deadline of the auction passed, I should close that auction, Send a notification message to both the item owner and the bidding winner to inform them.
how should I keep track of all open auctions? how could I monitor all their ending time and update the Auction status to be "Closed" on Real-time basis? ..
(1) Using SQL jobs ? .. that should reduce system performance .. shouldn't it ?
(2) A back-end service that is running on the server and uses Threading ? .. I have no clear background about that solution.

View 1 RepliesAdd Real Time MVC In Web Application
Mar 2, 2011I need to add a "real-time" element to my web application. Basically, I need to detect "changes" which are stored in a SQL Server table, and update various parts of the UI when a change has occured. I'm currently doing this by polling. I send an ajax request to the server every 3 seconds asking for any new changes - these are then returned and processed.
It works, but I don't like it - it means that for each browser I'll be issuing these requests frequently, and the server will always be busy processing them. In short, it doesn't scale well. Is there any clever alternative that avoids polling overhead?

View 2 RepliesPut Real Time Features Into Website Using PHP
Jun 3, 2010I'm looking for a way to put real time features into my web site. The idea is asynchronous communication between 2 people - like a chat session. If I use the chat example - I'd like the second person to know that the first one has sent a message to him, without refreshing or doing something active on the web page. Polling is not a good idea here - so is there any other solution? the back-end could be ASP.NET or PHP (ASP.NET preferred).

View 4 Replies.net - Using SqlCacheDependency To Get Real Time Updates?
Jan 9, 2010I would like to display real time updates on a web page (based on a status field in a database table that is altered by an external process). Based on my research, there are several ways of doing this.
Long Polling (Comet) - This seems to be complex to implement Regular Polling - I can have an AJAX method trigger a database hit every 5seconds to get the current status. But I fear this will have performance issues.
Then I read about using SqlCacheDependency - basically the cache gets invalidated based on a field in the table. I am assuming I can use the event trigerred when the cache is invalidated to show the new update to the user?

View 5 RepliesAjax - Implement Real Time Updates?
Feb 27, 2010I have seen several websites that show you a real time update of what's going on in the database. An example could be. A stock ticker website that shows stock prices in real time Showing data like "What other users are searching for currently.." I'd assume this would involve some kind of polling mechanism that queries the database every few seconds and renders it on a web page. But the thought scares me when I think about it from the performance standpoint.
In an application I am working on, I need to display the real time status of an operation that a user has submitted. Users wait for the process to be completed. As and when an operation is completed, the status is updated by another process (could be a windows service). Should I query the database every second to get the updated status?
Use Real Time Configurations In Application Without Restarting It?

I want to save configurations of those components somewhere and change them from back-end (administration panel) and the components use the updated configs but still application should not be restarted (changing web.config will result in application restart).
